We're also going to examine geophysical techniques that we use to locate shipwrecks and discover submerged worlds. These are both quite complicated subjects so please do use the Comments to ask questions which we can then answer to help bring on your learning.

Welcome to Week 3

Welcome to Week 3 of our Shipwrecks and Submerged Worlds course. This week we will develop your knowledge by investigating the changing maritime landscape, discussing sea-level change and learning about geophysical techniques for studying submerged landscapes and shipwrecks. We will also add more detail with regard to prehistoric boats and consider their preservation in the archaeological record, as well as exploring how we may identify these and more recent shipwrecks through survey.

This week may challenge you in different ways to last week, but, the ideas within it are key to how we practise maritime archaeology today. As such, don’t worry if something seems confusing at first and please do use the comments to ask additional questions.

By the end of this week you will be able to:

Describe the four main factors that affect sea-level and understand why these are relevant to maritime archaeology

Locate areas of the continental shelf that have been submerged since the last Ice Age and discuss potential survey methods for these areas

List geophysical techniques used in marine surveys

Identify shipwrecks in survey data

Differentiate between a variety of simple watercraft

This is a full and fascinating week and we hope you enjoy it!
